Semantic Information on Electronic Medical Records (EMRs) through Ontologies

This work shows the development of ontology in the domain of Electronic Medical Records (EMRs). The ontology supports vocabulary and semantic information to patients. The ontology implemented begins with the, the exploration of semantic web applications, ontology design ,analysis and the use of ontological engineering in order information indexing and retrieval from and to electronic medical records. This ontology is one of other services to incorporate on current telemedicine systems.Sociedad Argentina de Informática e Investigación Operativ

Introducing Wireless Grids Technology to the Field of Telemedicine

While telemedicine and technology-enabled education are not new concepts and have significant bodies of research, in depth application to management and treatment of veteran Post-Traumatic Stress Disorder (PTSD) and Traumatic Brain Injury (TBI) is relatively new. The conflicts in the Southwest Asia over the last two decades have significantly increased the need for healthcare and support services for these returning warriors. Creative thinking and innovative technologies are needed to meet the growing and changing demand of these patients in the face of many competing demands within the U.S. healthcare sector. This doctoral research study investigated the potential for a platform-agnostic (ad hoc) networking technology to serve as a trusted social networking and training platform for healthcare providers who are striving to provide quality healthcare that meets the needs of veterans suffering from PTSD and TBI. This research study analyzed the effectiveness of a digitally networked environment to deliver desired training and certification outcomes in a military healthcare environment. The level of acceptance of an ad hoc network technology (GridstreamRx) by healthcare professionals using it as an enabler of collaboration during the training process was evaluated. The results also assessed the readiness of healthcare professionals to use this Information Communications Technology (ICT), or analogous new applications and services, to help them perform their healthcare responsibilities. This thesis study, accomplished with the support of the U.S. Army and National Science Foundation, took place at two large military medical centers over a twelve-month period of time. Data was gathered from 568 healthcare professionals using quantitative survey instruments. Ninety-six respondents provided additional quantitative and qualitative inputs at various times during a proscribed training regimen. DeLone and McLean\u27s 2003 Information System Success Model, modified by findings of more recent research, provided the theoretical lens for analyzing the data from 32 of the training participants in determining the perceived net benefit of the GridstreamRx technology. The data gathered for the study showed, at the 95% level of confidence, that a majority of the professionals of these two medical centers would perceive a positive net benefit from using GridstreamRx in a healthcare training environment. The conclusion from this analysis was that not only are the healthcare providers in this study ready to use ICT and social networking in this professional setting, but also that GridstreamRx is an acceptable platform for performing these functions. The study participants provided input with respect to their priorities regarding information sharing techniques, functionality, and suggestions for improving the platform. The outcomes confirmed that GridstreamRx can be a successful introduction of ad hoc networking to telemedicine. This thesis concluded with recommendations for scholars and practitioners to pursue in the future; and should be followed up with further research and actions in order to build toward a Fully Integrated Virtual Healthcare Environment (FivHe)

Performance evaluation of cooperation strategies for m-health services and applications

Health telematics are becoming a major improvement for patients’ lives, especially for disabled, elderly, and chronically ill people. Information and communication technologies have rapidly grown along with the mobile Internet concept of anywhere and anytime connection. In this context, Mobile Health (m-Health) proposes healthcare services delivering, overcoming geographical, temporal and even organizational barriers. Pervasive and m-Health services aim to respond several emerging problems in health services, including the increasing number of chronic diseases related to lifestyle, high costs in existing national health services, the need to empower patients and families to self-care and manage their own healthcare, and the need to provide direct access to health services, regardless the time and place. Mobile Health (m- Health) systems include the use of mobile devices and applications that interact with patients and caretakers. However, mobile devices have several constraints (such as, processor, energy, and storage resource limitations), affecting the quality of service and user experience. Architectures based on mobile devices and wireless communications presents several challenged issues and constraints, such as, battery and storage capacity, broadcast constraints, interferences, disconnections, noises, limited bandwidths, and network delays. In this sense, cooperation-based approaches are presented as a solution to solve such limitations, focusing on increasing network connectivity, communication rates, and reliability. Cooperation is an important research topic that has been growing in recent years. With the advent of wireless networks, several recent studies present cooperation mechanisms and algorithms as a solution to improve wireless networks performance. In the absence of a stable network infrastructure, mobile nodes cooperate with each other performing all networking functionalities. For example, it can support intermediate nodes forwarding packets between two distant nodes. This Thesis proposes a novel cooperation strategy for m-Health services and applications. This reputation-based scheme uses a Web-service to handle all the nodes reputation and networking permissions. Its main goal is to provide Internet services to mobile devices without network connectivity through cooperation with neighbor devices. Therefore resolving the above mentioned network problems and resulting in a major improvement for m-Health network architectures performances. A performance evaluation of this proposal through a real network scenario demonstrating and validating this cooperative scheme using a real m-Health application is presented. A cryptography solution for m-Health applications under cooperative environments, called DE4MHA, is also proposed and evaluated using the same real network scenario and the same m-Health application. Finally, this work proposes, a generalized cooperative application framework, called MobiCoop, that extends the incentive-based cooperative scheme for m-Health applications for all mobile applications. Its performance evaluation is also presented through a real network scenario demonstrating and validating MobiCoop using different mobile applications
